The Bosch Rexroth R911308351 (MSK071D-0450-FN-S2-UG0-RNNN) is an IndraDyn S synchronous servomotor designed for applications requiring operation in environments with potential explosion risks, though it is not intended for continuous use in explosive atmospheres. It features a liquid cooling system, a plain shaft conforming to DIN 748 Part 3, and no holding brake. The motor has an EnDat 2.1 singleturn optical encoder with 2048 signal periods, a rotatable encoder connector (240°), and increased concentricity design. Key specifications include a continuous standstill torque of 20.0 Nm at 100 K, maximum torque of 66.0 Nm, continuous current at standstill of 17.6 A, maximum current of 69.3 A, and winding inductivity of 3,200 mH. The motor reaches 55°C during operation and should be cooled accordingly. Mounting is supported in horizontal or vertical positions, and electrical connectors are to be attached when de-energized. The unit is certified to UL and CSA standards.

Frequently Asked Questions

Why is a rotatable 240° encoder connector important during installation?

The connector rotation gives flexibility in tight spaces. The result is easier cable routing and reduced stress on connections.

How does the torque range support dynamic machine operations?

The wide torque span enables both steady continuous tasks and short bursts of peak performance. The versatility makes it suitable for demanding automation cycles.

What applications benefit from the compact D length design?

The shorter housing fits easily into restricted machine layouts. The compact build allows integration without compromising torque output.

Why is optical encoder technology preferred in this servomotor?

The optical system delivers high resolution with minimal signal noise. The accuracy improves synchronization in motion control tasks.

How does this motor handle overload situations?

The design tolerates short term high current peaks without performance loss. The protection features safeguard winding and drive components.
